Salamanders

Our life science text book says that salamanders have very strong legs. My students and I disagree.
Who's correct?

It's all relative, isn't it? Strong compared to what? And measured how? It's also dangerous to make sweeping generalizations such as that; there's tremendous variation among salamanders. Slender salamanders, for example, have tiny, delicate legs whereas hellbenders have massive, thick ones. If I had written the book, I wouldn't have said such a thing because it's vague and not very useful.
